l and shows the starting position of the 1 machine parts.

Figure 3 is a detail view of the teeth.

Figure 4 is an enlarged side elevation, partially in section, of the head;

Figure 5 is a front view of the machine.

The machine consists primarily of a sector 1 provided at its periphery with a series of curved blades 17 substantially as shown in Fig. 3. Cast with'the sector and diametrically opposed thereto is a counterweight 2 by which it is balanced during its rotation.

The whole is secured on a shaft 3 mounted for rotation in bearings carried by the frame 4. V Keyed on one end of the shaft 3 is a sprocket wheel 5 which transmits its rotational movement thereto; the said sprocket wheel is driven by a similarly toothed sprocket wheel 6' carried on shaft 7 which itself receives its movement from a transmission gear or any suitable prime mover in the direction of the arrow F, whereby a continuous rotational movement is imparted;

in the direction of the arrow F to the sector provided with blades.

Moreover, the shaft 7 has keyed at either end thereof a flywheel 8 which through the crank pin 9 and the adjustable rod lOvimparts an oscillatorymovement to the lever 11 rigid with the supporting arm 12. The system can oscillate aboutshaft'3.

The supporting arm 12 is formed at its upper end with a head 13 to which a slipper system 15 carried by an arm 16 is swingably mounted at 14. r V

The structure being adapted to oscillate 1931. Serial No. 534,411.

aboutthe shaft 3 under the control of the crank fly wheel 8 and the intermediate operating parts, it'can be moved away from the blades 17 by means of an eccentric gear 18 actuating the lever 19 rigid with the arm 16 through a powerful spring 20.

' The eccentric gear itself is operated as desired by the operator depressing the pedal 7 21 through a cable 22 actuating a lever 23, whereby the shaft 18'is partly rotated and the slipper 15 hinged at 14 iscaused to ascend or descend.

The machine operates as f0llows:-As suming the parts to occupy the position shown. in Fig. 2, the operator presents the hide while keeping it pressed with his body against the chest guard 24; he throws the free portion of the hide upon the side guards 25 at the same time asthe slippersystem towards or V is moved in the direction of the, arrow)? in Fig. 1; suflicient space is thus provided to place the hide on the side guards.

As soon as the portion of hide fed is positioned on the guards, the movement of the slipper 15 is reversed and same is swung towards the front end of the machine.

When the forward movement is completed, that is, as the slipper 15 reaches the breast guard 24, the blade-carrying sector 1 also reaches the said guard.

The movement of the slipper system 15 then is reversed again and takes place in the direction shown by the arrow f;'at the same time the blades 17 on with greater speed beneath the slipper 15 while the same is travelling from the front towards the rear end of the machine in the direction shown by thev arrow j".

It will be appreciated that during such" bearing movement of the slipper 15 the hide will be worked upon; Effectively, the said sector 1 travel I slipper-15 consists essentiallyof a flexible V belt 26 made of rubber or like material and running over rolls 27 and 28; the said slipper is provided with a stretcher 29 by which a suflicient tightness is imparted to the belt to make it tangent to the'general direction of the blade edges.

.The pressure of the 1 belt' on the blades thus sets up a tractive effort upon the hide, whereby same is stretched and softened, which is the desired result.

When the slipper system 15 has reached its rearmost position in the direction of the arrow f, the travel. of the blade-carrying sector beneath the slipper is wholly completed and the hide will fall loosely on the guards 25; as the slipper 15 is swung back in the direction of the arrow f, the same comes out of engagement with the guard 25, which allows the hide to be manipulated so that a portion thereof may be presented which has not been worked upon yet.

During each return movement in the direction of the arrow f, the operator has sufficienttime to move the hide worked upon at each stroke in the direction of the arrow f; thus, by successive actions all around the hide, the latter becomes entirely stretched and softened.

The eli'ect of the pedal 21 and of driving the slipper 15 towards the blades will be understood easily, such driving causing a tighter engagement to take place between the belt and the blades andincreasing the action of the latter upon stiffer portions of the hide, e.- g. the shoulder and butt.

This also allows softer portions of the hide to be treated with greater care.

In practice, a continuous wheel may be used instead of the sector 1, inasmuchas the blade bases are deeper than the guards 25; in such case, they same result would be obtained as with the balanced sector as described. I

I claim: 7

1. A machine for dressing hides and leathers, comprising a cylindrical member, at least a. portion of the periphery of the cylindrical ,member being provided with an abrading device, means for rotating. the cylindrical member, an oscillating system mounted about the axis of the cylindrical member and oscillatable by the means for rotating the cylindrical member, said oscilat the free end of the arm for stretching the hide or leather.

5. The machine set forth in claim 1, wherein the stretching means comprises a head oscillatable about the axis of the cylindrical member, an arm rotatably mounted on the head, means for elastically connecting the arm and the head, a plate carried at the free end of the arm, rollers rotatably mounted on the plate, an endless belt turning on the rollers and adapted to press the hide or leather against the abrading device on the cylindrical member, means for tensioning the endless belt, and means for pivoting the arm on the head.

6. The machine set forth in claim 1, wherein the stretching means comprises a head oscillatable about the axis of the cylindrical member, an arm rotatably mounted on the head, means for elastically connecting L the arm and the head, a plate carried at the free end of the arm, rollers rotatably mounted on the plate, an endless belt turning on the rollers and adapted to press the hide or leather against the abrading device on the cylindrical member, means for tensioning' the endless belt, means for pivoting the arm on the head, and an eccentric mounting between the arm and the head for varying the engagement between the belt and the abrading device, said eccentric mounting being manually controlled.

In testimony whereof I affix my signature.
